SPIKE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 600,052, dated March 1,1898. Application filed July 7, 1897. Serial No. 643,749. (No model.)

To all whom it may concern:

Be it known that I, LEWIS WILLIAMS, a citizen of the United States, anda resident of Johnstown, in the county of Cambria and State ofPennsylvania, have invented certain new and useful Improvements in SpikeMachinery, of which the following is a specification.

My invention relates to new and useful improvements in automaticmachinery for manufacturing railroad-spikes, and particularly to thatclass of spikes shown and described in Letters Patent to J. A. Markoe,No. 550,795, of December 3, 1895.

It is the object of my invention to construct a machine for producingrailroad-spikes .of special design from a bar of heated steel by aseries of operations, as will later be more fully described, and,further, to construct said machine in the simplest manner possibleconsistent with good work, durability, and ease of operation.

With the above objects in view I have devised the simple and novelconstruction shown in the accompanying drawings, forming a part of thisspecification, and upon which similar characters of reference denotelike or correspondin g parts throughout the several figures, and ofwhich Figure 1 is a plan view of my machine complete, excepting that thespike-tong mechanism is removed. Said machine is shown in the acts ofheading, grooving, and pointing spikeblanks. Figs. 1, 1, 1, 1, and 1illustrate the five operations of my machine necessary to produce acompleted spike. Fig. 2 is a rear elevation of my machine as seen fromarrow as of Fig. 1. Fig. 3 is an enlarged cross-section on line 3 3 ofFig. 1 and illustrates the spike-heading mechanism together with thegage for determining the length of stock to be used for each spike. Fig.4 isan enlarged cross-section on line 4 4 of Fig. 1 and illustrates theconstruction of the gripping-dies together with the spike-bending arm.Fig. 5 is an enlarged end view as seen from arrow 5 of Fig. 1 andillustrates the mechanism for operating the spike-bending arm 23.

Fig. 25 is a front end elevation of the pointing mechanism shown inFig. 23.-

enlarged side elevation of one of the pointing-hammers shown in thepreceding figures.

As before stated, my machine is entirely automatic in all its movementsand completes a spike in five operations upon the stock, as illustratedin Figs. 1 to 1, inclusive. Said operations are performed simultaneouslywith every complete rotation of the main drivingshaft and complete onespike with each series of operations.

Referring to the characters of reference marked upon the drawings, 1indicates the bed, which is mounted upon suitable legs. (Shown brokenaway in Fig. 2.)

2 indicates a driving-shaft which is journaled in boxes 3, secured tothe bed, and which bears a driving-pulley 4. From the above shaft allthe connections are made for operating the various parts of the machinewith but one eXception-namely, that of the pointing mechanism shown onSheets 1 and 11, which mechanism is preferably connected and operated bya separate belt from an independent counter-shaft.

A represents the stock, (see Fig. 1,) which may be continuously fed tothe machine from a long furnace by any ordinary feed mechanism, (notshown,) or it may be heated in convenient lengths and fed to the machineby an attendant. As will be seen, the stock passes through a stationarydie 5, contained in the raised part 6 of the bed, and is fed against amovable stop 7, which determines the length of the stock required for asingle spike. After the stock has been fed in, as above specified, thefirst operation thereon is to cut a blank therefrom, which cutting isdone by mechanism shown in Figs. 1, 4, and 8 and which I will nowdescribe.

The raised part 6 of the bed is provided with a suitable way 8, in whichis fitted a slide 9, carrying cutting and clamping die 10, the latterbeing held firmly in position by means of the clamping-plate 11. (SeeFig. 4.) The slide 9 is actuated from a cam 12 upon the maindriving-shaft 2 through toggle connection 13, link 14, andsupporting-lever 15, (see Fig. 14,) said link being provided upon oneend with a roller to engage a groove of the cam aforesaid, while theopposite end is directly connected with the toggle before mentioned.

From the foregoing costruction it will be apparent that with eachcomplete rotation of the driving-shaft the cam 12 thereon will throw thelink 14 to and fro, thus opening and closing the toggle in a manner tooperate the slide forward and backward. Said forward movement will cut ablank from the main stock and carry the same slightly to the left, asseen in Fig. 1, where it is held against the stationar die 16,said diebeing practically a counterpar of the movable die carried by the slideand is clamped to the portion 6 of the bed by means of a clamping-plate17,as shown.

The blank is held between the dies aforesaid during the headingoperation,as is clearly shown in Figs. 1, 3, and 5, the forward endprojecting slightly upon the inside in a manner to be operated upon, aswill next be described. The first operation upon the blank while in theabove position is to bend the free end over, as shown in Fig. 1". Thisoperation is performed by mechanism shown in Figs. 1, 4, 5, and 6, whichconsists of a rock-shaft 18, j ournaled in suitable boxes 19, bearing anarm 20, the free end of which is provided with a roller to engage agroove 21 in the periphery of the cam 22, secured upon the main shaft.The opposite end of the rock-shaft 18 is provided with a bending-arm 23,having a removable hardened head 24 fitted in the outer end thereof, asis clearly shown in. Figs. 6 and 7. The purpose of said head is toengage the free end of the blank and turn it over at an angle of aboutsixty degrees, or substantially as shown in Fig. I Said operation isperformed and the arm 23 returned to its normal position with eachcomplete rotation of the main driving-shaft.

After the end of the blank has been turned over, as shown, the headingoperation takes place and is performed by the following mechanism, (seeFigs. 1, 3, and 8:) The bed 1 is provided with ways 25, in which isfitted the slide 26, actuated through link 27 by a crank 28 upon themain driving-shaft. The slide 26 is provided with a detachable block 29,which is clamped therein by means of screwbolts 30 and serves to retainthe heading-die 31 in its proper position. The forward end of saidheading-die, together with the face of the dies 10 and 16, are suitablyrecessed to receive the surplus stock of the end of the blank and byreason of the pressure brought to bear forms the same into the desiredshape or head, said operation being completed with one rotation of themain shaft.

The stop 7, which serves to limit the forward movement of the stock A,is a movable affair and is raised and lowered with eachforward-and-backward movement of the slide 26 in accordance with thefollowing mechanism: Upon one of the ways 25 is secured a bracket 32, towhich is pivoted a swinging arm 33, carrying a roller 34, which latterprojects inward and is engaged by an inclined fork 35, secured to theslide 26 aforesaid in a manner to engage the roll 34 when the slide isin its forward position and to disengage the same when in its retractedposition. Upon the forward end of the arm 33 is secured an adjustableblock 36, to which the stop 7 before mentioned is pivoted. The upperendof this stop is connected by means of a link 37 with an adjustable screw38, secured in a bracket 39. By the above construction it will beobvious that different lengths of blanks can be secured by adjusting theblock 36 and the screw 38, which parts control the raised and loweredpositions of the stop 7. After the blank has been headed the spike isremoved from the dies 10 and 16 and placed in one of a series of fiveholders mounted upon an intermittently-rotary table, ('shownon Sheets 1and 8,) the construction of which willlater be'de-- scribed. Themechanism for removing a spike from the dies as above is fullyillustrated on Sheets 5 and 6, together with Figs. 1 and 2, and willnext be described.

Upon the bed-1 of the machine (see Figs. 1 and 2) is provided asuitablepedestal 40, which supports the spike-removing mechanismreferred to and is made of a shape to most conveniently accommodate saidmechanism. Upon said pedestal is provided boxes 41, in which isjournaled a shaft 42, preferably at an angle of about thirty degreeswith respect to the main bed of the machine. Said shaft bears a gear 43,which meshes with and is driven by a gear 44 upon an intermediate shaft45, mounted in bearings '46, Fig. 2, secured to the bed and operatedfrom the main driving shaft through bevel-gears 47, as shown. Theconnection between the main drivingshaft 2 and the shaft 42 is such thatthe latter is driven at the same rate of speed, thus insuring this partof the machine working in unison with the other. 40 is further providedwith bearings 48 for the purpose of slidably supporting a hollow shaft49. Upon said hollow shaft is securely keyed a grooved collar 50, whichlatter is engaged (see Fig. 13) by pins 51 of a forked arm 52, pivotedto the frame at 53 and bearing a roller upon its opposite end, whichengages the groove 54 in cam 55 upon the shaft 42. From the above itwill be seen that with each rotation of the shaft 42 the hollow shaft 49is subjected to a slight raised and lowered movement in addition to arocking motion,

'which will later be described. Within the hollow shaft is journaled asolid shaft 56, and to the upper end thereof is secured a small pinion57, engaged and actuated by a segment 58, carried upon a bell-cranklever 59, pivoted to a bracket of the main frame. The operated end ofthe bell-crank lever (see Fig. 10) is provided with a roller to engage agroove in the face of cam 61 upon the shaft 42 and serves as theoperative connection therefor.

It will be seen from the above construction that with each rotation ofthe cam 61 the bell-crank lever carrying the segment is operated in amanner to turn the pinion 57 and its shaft approximately three-quartersof a rotation. The throw of the cam, however, is such as to divide saidturn into substantially two distinct movements, the primary one of whichis about one-quarter of a turn and the second the remainder or onehalfof a turn. The first of said movements serves to clamp the spike and thesecond to throw the tongs from one side to the other of its shaft.

Upon the hollow shaft 49 is clamped a rigid arm 62, the extreme end ofwhich forms one member of a pair of tongs of which the operative member63 is pivoted at 64 and is provided with a link 65, which is connectedto a short arm 66 (see Figs. 11 and 12) upon The pedestal the solidshaft 56. Upon the inner portion of the arm 62 I provide lugs 67,hearing adjusting stop-screws 68, which, as will be seen, are in directline of travel of the arm 66 and serve to be engaged thereby.

The operation of moving a spike from the dies by the above mechanism isas follows, the parts being in the position shown in Fig. 9: The cam 55acts to operate the forked arm 52 in. a manner to lower the shafts 56and 49, together with the tongs, which latter are lowered while openinto the recesses of the dies 10 and 16 in a manner to straddle thespike about midway of its length. The next operation is a one-quartermovement of the shaft 56, actuated by the segment upon the lever 59,which movement through the arm 66 and its connection 65 closes the jawsof: the tongs in a manner to firmly grasp the spike thereon. One of thescrews 68 is so adjusted as to cause the arm 66 to abut thereagainst atthe instant the spike is firmly clamped, at which instant the die 10also moves backward, freeing the spike, and. at which time the forkedarm 52 again acts in a manner to raise the shafts to the position shownin Fig. 9. Upon, being raised to said-position additional rotarymovement is imparted to the shaft 56, which through the connection ofthe arm 66 and the screw 68 throws the tongs around to the oppositeside, after which the forked arm 52 is again operated in a manner tolower the shafts, together with the tongs and spike,

which places the head of the latter between one of a series of pairs ofjaws constituting holders mounted upon an intermittently-rotary table B,journaled in the bed. Upon being placed therein as above the jaws areclosed u pon the head by mechanism which will later be described. Afterthe spike has been grasped by the holder the tongs are opened, raised,and returned for another spike and the former operation repeated.

The intermittent rotary table 13, above referred to, will be nextdescribed, and attention is called to Sheets 1, 7, and 8, which fullyillustrate its construction and operation. Within the bed 1 is provideda bore 69, in which is journaled the hub of a ratchet-wheel 70, and towhich is keyed the hub 71 of the table B aforesaid. To the under side ofthe bed I secure a bracket 72, Fig. 14, in which is mounted a verticalcentral post 73. Upon the upper end of the said post is secured a cam74, which serves to operate the holders carried upon the table, as willpresently be described. Upon said post 73 is also journaled an arm- 75,(see Figs. 14, 16, and 17,) carrying a pawl 76 to engage notches 77 ofthe ratchet-wheel 70, before mentioned, se-..

bell-crank lever is connected one end of a link 80, the opposite end ofwhich is connected with and operated bya crank 81 upon a short shaft 82,journaled in the bed, the upper end being provided with a bevel-pinion83, meshing with and driven by a similar pinion 84 upon the maindriving-shaft. Said bell-crank lever is further provided withadjusting-screws 84, which are mounted in lugs of the arm 75. Forwardmovement is imparted to the table B from the main driving-shaft witheach rotation thereof through bevel-pinions S3 and S4, crank 81, link80, the bell-crank lever 78, and its arm 75. The purpose of thepreliminary swing of the bellcrank lever from the position shown in Fig.17 is to first disengage the holding-pawl 79, so as to free theratchet-wheel. A continued movement of the link will cause said levertostrike the adjustable stop 84" upon the arm 75, which later through itspawl moves the ratchet-wheel and table just one-fifth of a turn, whichmovement is sufficient to carry a spike from one station to anotherviz.,from the receiving-station C, where it is placed by the tongs, to thegrooving mechanism, (designated by D,) or from the grooving mechanism tothe pointing mechanism shown by E.

As before stated, the table B is provided with a series of holders F,all of which are of a similar construction, as will be apparent fromFigs. 14, 15, and 18. Therefore I will refer to all with like referencecharacters. Each of said holders F consists of two jaws, one being fixed(designated by 85) and the other movable, which I designate by 86. Thefixed jaw is secured to the table by means of a screw-bolt 87 andcarries a steel grippingdie 89. Both said jaw and die are madeadjustable by means of a screw 89, as shown. The swinging jaw is pivotedto the screw 87 and is also provided with a die 88, which latter is heldin said jaw by means of a clamping-plate 90 and a screw 91, as shown.Said swinging jaw is further provided with a roller 92 upon its outercorner, which is for the purpose of engaging the several inclines a, b,c, and (1 upon the fixed cam 74..

From the foregoing it will be seen that with each intermittent rotarymovement of the table the roller upon the several movable jaws will moveupon the face of the cam and be engaged by the inclines aforesaid in thefollowing manner: The roller of the movable jaw as it starts from thefirst station 0 rides up the incline a in a manner to move said jaw andclamp the spike and head, whereupon the movement of the table iscontinued until said jaws approach the grooving-station D, when saidroller will ride up the second incline b, which causes the said jaw tofurther tighten upon the head and hold it perfectly rigid during thegrooving operation, during which time the table stands still. A furthermovement of the table will carry said spike to the pointing mechanism E,the roll riding down the incline b, loosening up slightly on thespike-head until the pointing-station is reached, when, as beforestated, a third incline cis reached and the head is again tightlyclamped and held during the pointing operation. After the pointing isdone and the spike is completed the table is given a further rotation,thus causing the roll of the jaw in question to ride down an incline d,which frees said jaw in a manner to release the spike, which drops fromthe machine at e. It is further obvious that the several holders F onthe table operate successively and that there are spikes in three ofthem at all times.

The spike having been carried by the table B from the station 0 tostation D is ready to be operated upon by the grooving mechanism, whichwill next be described. (See Sheets 1, 9, and 10.) Upon the maindriving-shaft 2 is a spiral gear 93, which meshes with and drives asimilar gear 94 upon a shaft 95, journaled in boxes 96, secured to themain bed. Said shaft 95 is provided with a crank 97, upon which isjournaled a box 98, slidably fitted in a yoke 99, with a reciprocatingslide 100, mounted in boxes secured to the bed. Upon the forward end ofthe slide is mounted four pairs of cars 101, the side ones of which havepivoted thereto arms 102, which are normally thrown outward by means ofa spring 103. Within the forward inner end of said arms are mountedgrooving-rollers 104, which (see Fig. 21) serve to form the groove inthe spike. Said rolls, as will be seen, are rotatably mounted upon a pinand their periphery is engaged by an intermediate roller 105, mounted inthe arm 102 and engaging the track of movable block 115. To the top andbottom ears 101 of the slide are mounted arms 106, which like the sidearms are provided with inner rollers 107, whose periphery is smooth andforms the flat side of the spike-shank. Said rolls are backed byintermediate rollers 108, the bottom one of which engages a track in thebed, while the top one rolls in a corresponding track in a bridging 109.The top and bottom arms and rolls, as will be apparent, simply have acommon reciprocating movement, while the side ones have a reciprocalmovement in addition to a slight inward and outward movement necessaryto enter the stock of the spike and to spread open again when retractedto straddle the new blank to be grooved, as will later be again referredto.

Upon the shaft 95 are mounted two cams 110, which, together with theirconnecting parts, are exact duplicates of each other and work in unisontherewith. Therefore I will refer to them with like characters ofreference. Beneath the cams are mounted, in suitable ways 111, slides112, which, as will be seen from Figs. 19 and 22, are provided with lugs113, which engage the cam upon each side, so as to be positivelyoperated thereby in both directions. The forward ends of the outside ofsaid slides (see Figs. 20 and 21) are provided with a suitabledovetailllG, which slidably operates in a corresponding way in anadjustable block 117, the latterbeing secured to the main bed of themachine and made adjustable by means of screws 118.

The inner forward sides of said slides are in like manner provicled'with a way 114, which engages a corresponding way in a movableblock 115,'which, as will be seen, is fitted between lugs 119 of thebed. The inner sur-.

the same inward, thus bearing the rib of the grooving rollers 104 intothe spike, after which the slide 100 is drawn backward, thereby rollingthe groove in the spike.

Having thus completed the description of the grooving mechanism, 1 willnextdescribe the pointing mechanism, by means of which a spike'iscompleted. 7

The pointing mechanism is fullyillustrated on Sheets 1 and 11, andconsists of the following: Within boxes 120 is journaled a shaft 121,having bevel-gear connections 122 with the shaft 95 before mentioned,and by means of which the same is operated. Upon the opposite'end ofsaid shaft 121 is secured a crank 123, bearing a link connection 124with an arm 125 upon a rock-shaft 126, journaled in a suitable boxsecured to the bed. The, op-

posite end of said shaft is provided with a similar arm 127, which inturn is provided with a link connection 128 with a slide G, secured inways 129 of the bed. From the above construction it will be seen thatwith each complete rotation of the shafts above named the slide G,together with the parts mounted thereon, will be thrown forward andbackward, asdesired.

- The slide G consists of a specially-designed casting having aface-plate 130 and carries five longitudinal shafts, as will be apparentfrom Fig. 27. The main shaft 131 (see Fig. 24) is journaled in thecentral rear portion of the slide and is provided with a belt-pulley 132upon its outer end, by means of which it is driven at a high rate ofspeed from an independent source. The inner end of said shaft isprovided with a pinion 133, which meshes with and operates four largerpinions 134:, mounted upon separate shafts 135, jour-- naled in theslide,-as shown. Each of these shafts is provided with acrank 136,bearing a journal 137, which is slidably fitted in a reciprocatinghammer 138, the latter being suitably mounted within recesses of theslide and covered by'the plate 130'aforesaid.

The forward ends of the hammers 138 are provided with hardeneddetachable heads 139, as fully appears in Fig. 28, which head inpractice comes in direct contact with. the heated spike and operatesthereon. As will be seen from a careful inspection of the position ofparts shown in Figs. 25 and 26, the hammers are timed to operate inpairs, the upper and lowerhammers operating together and the sidehammers voperating therebetween that is to say, the two side hammersbeing out in their extreme position while the upper and lower ones areat their inner extreme, thus allowing each to come closely togetherindependent of the other. The operative end of the head 139 is slightlybeveled, as will be seen from Fig. 24,which is to insure the propertapering of the end of the blank. From the above construction it will beobvious that rotary movement is imparted to the several shafts 135 fromthe independentlybelted shaft 131 and that by such rotary movement arapid reciprocal movement will be imparted to the hammers in question,the force of which is directly applied to the end of the spike. Saidoperation is started whenthe slide is nearing its extreme forwardposition and is completed at the beginning of the retracted movement ofthe same, which completes the portion into a head, rollers or theirequiva-' lents provided with ribs for forming grooves in two sides ofthe shank portion, and mech-.

anism for pointing the end of said grooved shank.
